45min of integral LRGB exposure of Neptune and Triton (29au away) captured remotely using Telescope #1 (ASA-RC D = 1m f/6.8, FLI ProLine 16803) system of ChileScope observatory, over 2 imaging sessions carried out with the interval of almost exactly 3 days apart on Oct 9, 2020 and Oct 12, 2020.

Only 3x 90s frames were obtained during the first observation session, so compensation for proper motion of Neptune wasn't necessary. The acquisition session lasted for 40 min during the second observation session, and also seeing was much better, so compensation for proper motion of Neptune was necessary.

The time gap between the sessions matched almost precisely (0.51x) half of the period of rotation of Triton around Neptune so it appears on the opposite sides of Neptune, as expected, with angular separation of 16" from the main body.

The brightest star in this entire field is of +12.5m magnitude.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
